PERFORMANCE CURVE 50Hz

Curve specifications The specifications below qualify the curves shown on the following pages. Tolerances according to ISO 9906 Annex A The curves refer to effective speed of asynchronous motors at 50 Hz Measurements were carried out with clean water at 20°C of temperature and with a kinematic viscosity of ν = 1 mm2/s (1 cSt) In order to avoid the risk of over-heating, the pumps should not be used at a flow rate below 10% of best efficiency point. Symbols explanation:

Q = volume flow rate H = total head
